巷道是矿山的动脉 ,巷道贯通成巷质量不仅影响着巷道的使用功能 ,而且也关系到人力、物力和时间的投入。因此 ,保证贯通巷道掘进工作面沿设计几何轴线掘进 ,使贯通接合点的横向和竖向偏差值在工程容许范围以内 ,是矿山测量人员的重要职责。贯通工程按施测路线在贯通重要方向上 The roadway is the artery of the mine. The quality of the roadway penetrating into the lane not only affects the function of the roadway, but also the input of manpower, material resources and time. Therefore, it is an important duty for mine surveyors to ensure tunneling along the design geometrical axis of tunneling through roadways, so that the horizontal and vertical deviation values ​​of through joints are within the allowable range of the project. Through the project by measuring the route in an important direction through
